Actor and role matrix: who performs and who approves each role

Five actors down the side, five business roles across the top. Performs marks the actor who carries out the role and Approves marks the actor who signs off its output, so accountability is explicit before any process design starts.

Actor and role matrix: who performs and who approves each role An Actor/Role Matrix, the TOGAF Standard 10 Phase B artifact, worked for London Grid Distribution. Five actors run down the side, from the connections customer to the regulation analyst, and five business roles run across the top. Each cell records Performs or Approves. The emphasised Network planner row performs or approves four of the five roles, the concentration this matrix exists to expose, and no actor both performs and approves the same role.

The Network planner appears in four of the five role columns. That concentration is the finding: one person away stalls assessments, outage releases, asset data and publication sign off at once. Performs and Approves for the same role must sit with different actors.

In Phase B, before process design, to make accountability explicit and keep performing and approving apart.
